Charlie Sheen has revealed that he doesn’t “recognise parts” of himself when he looks back on his “cringeable” behaviour from last year.The 46-year-old actor, who suffered drug and alcohol problems in 2011 before being axed from hit TV series ‘Two and a Half Men’, has apologised to the public for his actions last year, and has compared his wild behaviour to having an out-of-body experience.”I didn’t recognise parts of who that guy was. I just wish it was somebody else’s body. You say it’s been a year – it’s either been a day, or a hundred years,” Contactmusic quoted him as saying. Sheen joked that it was a ”team effort” which led to him ultimately overcome his drug and alcohol issues, but admitted he didn’t have many friends through his troubled time.
